🌐 What is Web Security?
Web security refers to the practices and technologies used to protect websites and web applications from unauthorized access, data breaches, and malicious attacks. It ensures the confidentiality, integrity, and availability of data transmitted between users and servers.
🛡️ Key Concepts
- HTTPS: Secure communication protocol (🔒) using SSL/TLS certificates.
- Authentication: Verifying user identity (👨💻) through passwords, tokens, or biometrics.
- Authorization: Granting access permissions (🔑) based on user roles.
- Input Validation: Preventing malicious inputs (🚫) like XSS or SQL injection.
🚨 Common Web Attacks
- SQL Injection (⚠️) - Exploiting database vulnerabilities.
- Cross-Site Scripting (XSS) (⚠️) - Injecting malicious scripts into web pages.
- Cross-Site Request Forgery (CSRF) (⚠️) - Trick users into performing unintended actions.
- DDoS Attacks (⚠️) - Overloading servers with traffic.
🛡️ Defense Strategies
- Use firewalls (🛡️) to block malicious traffic.
- Implement rate limiting (⚡) to prevent brute-force attacks.
- Regularly update software to fix vulnerabilities (🔄).
- Use WAF (Web Application Firewall) tools like ModSecurity for advanced protection.
